The present invention relates to a commodity delivery device forcoin-freed apparatus.

Commodity delivery devices are already known in which a pressure footrests upon the uppermost package of a pile of commodity packages, andwhich pressure foot is connectedto a guide that may slide freely along acolumn. This construction, however, has the essential drawback thatduring the ejection of the uppermost package, the guide is not heldsecurely but constantly has a tendency to slide downwards, so that thepressure effectuated on the next package inthe pile will be such thatthis package is moved from its position within the commoditycompartment.

The object of the present invention is to provide means for overcomingthis drawback in a commodity delivery device of a coin-freed apparatus,and according to the invention thisobje'ct is attained by means of abellzcrank lever pivoted on a slidable platform, the said bell cranklever being actuated by means of a coin-freed eiectromagnet in such amanner that it ejects the uppermost package of a pile of commoditypackages, and at the same time actuates means for locking a ratchetwheel mounted within an extending part of the platform on a fixedthreaded spindle, so that the platform is prevented from slidingdownwardly. Upon the bell crank lever being released by theelectromagnet, it returns by means of spring pressure to its initialposition, at the same time releasing the means locking the ratchet wheelthat may thus rotate on the fixed threaded spindle to allow the platformto slide down to a position for ejecting the next package in the pile ofcommodity packages.

The invention is described in detail in the iollowing description andthe accompanying drawing, in which Figs. 1, 2 and 3 illustrate a deviceaccordin to the invention seen in top elevation, in front elevation, andin side elevation respectively. Fig. 4 is a sectional view on line aa inFig. 1, and Fig. 5 is a sectional View on line b-b in Fig. 2. I

l and 2 indicate the upper and the lower plates of a commoditycontainer. These ends are assembled means of spacing rods 3. Within thecontainer there is placed a stack of commodity packages 5, which inFigs. 3 and 4 are indicated by dotted lines. Slidable on the spacingrods 3 there is a platform 8 which carries an upwardly extending fixedarm 9. The platform 8 is slidable by means of guide members 23 slidableon the rods 3. By means of a pivot Ill on the arm there is rotatablymounted a bell crank lever H, which at the extreme end of the one 3Claims. (Cl. 312-63) arm has a plate l2 that extends behind theuppermost package 1. Furthermore this arm has at its lower end a branch13 with a pressure foot M that rests with its foot upon the uppermostpackage 1 in the pile of packages. To the other arm of the bell cranklever there is attached a cord [8 that is connected to an electromagnetnot shown in the drawing. The'platform 8 is provided with a rearwardlyprojecting U-shaped extension l5 providing a space within the bend for ahorizontally disposed ratchet wheel 16. This ratchet wheel is internallythreaded so that it may be screwed on to a threaded spindle ll rigidlydisposed between the ends I and 2 of the commodity container. The threadof the spindle is such that the ratchet Wheel is not self-lockiiig. Theratchet wheel I 6 may be locked against rotation by means of a pawl 26mounted on a pivot l 9 on the extension I 5 in such a manner that it mayengage the teeth of the ratchet wheel.

On the bell crank lever there is a lug 22 that nore mally holds the pawl20 out of engagement with the ratchet wheel 16.

The device operates in the following manner; F When the coin-freedapparatus comprising the commodity delivery device is actuated by theinsertion of a coin, an electric circuit is closed through anelectromagnet, not shown in the drawing, and a pull is exerted on thecord 18. The bell crank lever H to which the cord I 8 is connected isrotated on its pivot 10, and its depending arm with the plate l2 ejectsthe uppermost package out of the commodity container through an outletopening not shown in the drawing. By this movement of the lever, the lug22 releases the pawl 20 which by its weight drops to engage the teeth ofthe ratchet wheel l6, and thus prevents this wheel from rotating on thefixed spindle l'l. Thus the platform 8 cannot slide downwards as long asthe bell crank lever is in its ejecting position on account of theextension containing the ratchet Wheel. When the pull of the cord 18ceases, the bell crank lever II will return to its inactive position bythe actuation of a spring 2 I. During this return movement of the bellcrank lever the lug 22 will again raise the pawl 20 and thus release theratchet wheel l6, which rotates on the spindle owing to the weight ofthe platform, which thus slides downwards until the pressure foot 14abuts the now uppermost commodity package in the pile.

I declare that what I claim is:

1. In an article delivery device for a coin-freed apparatus, thecombination of a number of vertical spacing rods between two horizontalend plates, 2. platform slidable on the spacing rods, an upwardlyextending arm attached to the platform, a spring actuated bell cranklever pivoted to the upper end of the said arm and adapted to beactuated out of itsinactive position, a ver tical plate member attachedto the lower end of one arm of the bell crank lever and so disposedadjacent the top of a stack of articles on the platform as to eject theuppermost article of a stack of articles when the bell crank lever is actuated, a forwardly and. downwardly extending presser foot attached tothe lower end of the other arm of the bell crank lever and resting u onthe uppermost article in the stack, a rearwardly projecting U-shapedextension on the platform. a vertical threaded spindle rigidly fixed tothe end plates and passing through the, said extension, an internallythreaded ratchet wheel mounted on the spindle and disposed within theextension, a pawl pivoted on the extension and disdisposed to engagedand lock the ratchet wheel during the actuation of the bell crank leverwhile ejecting the uppermost article, and a lug on the bell crank leverfor raising the pawl out of engagement with the ratchet Wheel upon thereturn movement of the bell crank lever to its inactive position topermit said platform to be lowered and the presser foot of the bellcrank lever to contact the uppermost article of the stack.

2., In an article delivery device for a coin-freed apparatus; thecombination of a number of vertical spacing rods between two horizontalend plates, a platform slidable on the spacing rods.- a bell crank leverpivotally mounted on the platform and adapted to be actuated out of itsinactive position, a member secured to the. lever in position to ejectthe uppermost article of a stack of articles when the lever is actuated,a presser foot on the lower end of the lever and adapted to rest uponthe uppermost article inthe stack. a rearwardly projecting U-shapedextension on the platform, a vertical threaded spindle rigidly fixed tothe end plates and passing through the extension, an. internallythreaded ratchet wheel mounted on the spindle and disposed within theextension, a pawl pivoted on the extension and disposed to engage andlock that ratchet Wheel during the actuation of the lever while ejectingthe uppermost article, and a lug on the lever for raising. the pawl outof engagement with the ratchet wheel upon the return of the lever to itsinactive position to permit said platform to be lowered and the presserfoot of the bell crank lever to contact the uppermost article of thestack.

3. In an article delivery device for a coin-freed apparatus, thecombination of a number of vertical spacing rods between two horizontalend plates, a platform slidable on the spacing rods, a bellcrankleverpivotally mounted on the platform and adapted to be actuated out of itsinactive position, a member secured to the lever in position to ejectthe uppermost article of a stack of articles when the lever is actuated,a presser foot' on the lower end of the lever and adapted to rest uponthe uppermost article in the stack, an extension on the platform, avertical threaded spindle rigidlyfixed to the end plates and passingthrough the extension, an internally threaded ratchet wheel mounted onthe spindle and disposed within the extension, a pawl pivoted on theextension and disposed to engage and lock the ratchet wheel during theactuation of the lever while ejecting the uppermost article, and a lugon the lever for raising the pawl out of engagement with the ratchetwheel upon the return movement of the lever to its inactive position topermit said; platform to be lowered and the presser foot of the bellcrank lever to contact the uppermost article of the stack.
